Gain Muscle. Maintain Progress
Free · Designed for iPhone. Not verified for macOS.
Tired of complicated setup before you can even log a single rep? GainTain gets you tracking your workouts INSTANTLY – no account required! Dive right into logging your exercises, sets, reps, weight, and even supersets with our intuitive interface.
- Apple Watch is here.
Log sets from your wrist, control rest timers with the Digital Crown, and track cardio with live heart rate — even when your phone's in the locker. Streaks and your next workout are available as watch face complications.
- Cardio, fully built out.
Programmable interval workouts, live distance and heart rate, a persistent mini-player so you can navigate the app mid-run, and goals and trends to see where you're heading. Everything syncs to Apple Health.
- Eat like you train.
Scan a barcode, snap a photo, or just describe your meal — food logging now takes seconds. Macro visualizations show how nutrition connects to your training. Water and supplement tracking round it out.
- A Progress tab worth opening.
A redesigned four-tab layout with an estimated 1RM trend, a muscle recovery heat map, a multi-signal activity calendar, and side-by-side progress photo comparison.
- Smarter workouts.
Auto-generated workouts, progressive overload prompts, weight suggestions based on your last session, supersets, RPE tracking, and an exercise guide with demo images.
- Your coach checks in.
Proactive check-ins from your AI coach, plus gym and measurement reminders that arrive when they're useful.
- Plus offline support so a bad signal never costs you a set, full data export and deletion, and a large number of bug fixes and performance improvements.
- We've removed the money-staking feature to focus on the training experience.
